December is an ideal time to plan a garden reset or makeover in preparation for the following spring and if not practising already why not try cold frame gardening. Cold frame gardening is a method of planting different types of green life, mainly produce, in a microclimate created by a man-made structure. The addition of a cold frame within the garden enables the growing season to be extended. They are versatile, require little surface area, ideal for a small garden and are easy to build, alternatively, they can be purchased flat pack or ready-made from an established retailer. Essentially a cold frame is a bottomless box with a skylight, a halfway house between a greenhouse and exterior planting. They can be positioned directly onto any garden bed and assist in warming bare soil in early spring. The transparent lid allows the sunlight to enter and simultaneously prevents heat loss by convection which would otherwise normally occur, particularly during the night. Thus, a microclimate is generated with an increase in soil and air temperature and also providing protection against the elements, such as strong wind, rain, hail and even snow. Plants can be started earlier in spring, such as seedlings which can then be transplanted to open ground once established. A variety of produce can be grown in a cold frame, the most popular being lettuce, spinach, kale and green onions. However, a variety of root vegetables and brassica can be grown too. When deciding to position the cold frame, take in consideration that full sun is essential and the transparent cover should slope downwards at a slight angle facing southwards to absorb the heat from the sun and to allow for rain run off. A cold frame can be constructed from any material, the sides being of a solid material such as wood or masonry and the top being of a transparent material such as glass. A wooden structure can look aesthetically pleasing as well as being portable too, whereas, brick or block structure will be a more permanent feature and choice of location should be greatly considered before building. The most simple method of construction being straw bales used as sides and an old disused glass window or door placed on top. Imagination is key! It can be designed and built to suit your particular needs, hinges and handles attached for ease of opening the cover and if preferred one crop could occupy the entire cold frame or a combination of crops in rotation to provide produce throughout the year. It is important to ensure the transparent cover is clear from any debris, as this will inhibit heat absorption and with crops being under cover, regular watering will be required. Increased humidity can be a problem within a small enclosed area, therefore, allow for slight ventilation within the cold frame structure. Specific frame designs are available so they can be positioned on a hard landscaped surface such as paving. These can take on the appearance of a miniature greenhouse and more suitable for potted plants. Cold frames are cheap to buy, easy to build and easy to maintain. They can be sited directly onto a garden bed, gravel or a paved surface and are a valuable addition to any garden, large or small. A mobile and modular solution for growing plants, lower in price and occupying less space in comparison to a greenhouse, there are many advantages of cold frame gardening. contribution from Oliver David Cook

They maybe all around us now and covering large areas of the garden, often regarded as a hindrance when it comes to the maintenance of a neat and tidy garden. But, alas, leaves falling to the ground is a message from nature which one should take heed of, and that message being leaf matter is the best natural and free mulch available for the gardener and grower.
Fallen leaves can be found residing in many areas, from resting on the lawn to wind blown corners of the garden and now is the time to sally forth and gather. A large pile of leaves can be transmuted into leaf mould, the decomposed matter formed when the leaves have decayed over time. The leaves can be stored in plastic bin liner bags with a few holes pierced in the sides and bottom, once full, a sprinkling of water is advisable then storage in a shady area of the garden is essential and the following autumn the rotten leaves form a crumbly rich surface mulch. To be left for a second or third year will allow for increased decomposition of the leaf matter and this, with its added microbes, can then be used as a conditioner and soil enhancer which can be dug into the soil to aid in water retention for drier ground and for improving drainage in heavier soils. If preferred a leaf storage bin can be constructed and there are numerous methods of construction, one composed of chicken wire which permits air to travel through, being the most simple. Once a large amount of leaves have been placed into the bin, apply a sprinkling of water and then cover with some black plastic sheeting on top to encourage the decomposition. Leaf mulch is high in nutrients which will pass slowly into the ground below. As with all mulches it prevents the ground from drying out during the summer months and from becoming too cold or even freezing in the winter months. It also reduces the opportunity for the unwanted plants referred to as weeds to grow. The leaves can be gathered regularly as they fall with hand tools such as a rake or broom, a lawn mower can be used on a higher setting to collect leaves from the lawn whilst shredding at the same time. If the leaves are not collected soon after falling, then they will dry out and loose their nutrients. If your own garden is devoid of fallen leaves then maybe ask the neighbours, I am sure they would be happy with the assistance of leaf clearing. Or vice-versa, others in the neighbourhood may require leaf mulch too. The coming together can create a community free leaf mulch, this way the local gardens will never be without a mulch or compost. It is advisable to avoid leaves which have been lying on roadsides, they may contain toxins. Certain leaves will break down faster than others, Horse Chestnut leaves taking longer than Oak leaves. The leaves from Walnut and Eucalyptus do contain a natural herbicide, this may inhibit the growth of plants within the area the mulch or mould is applied. The splendour of the autumnal colours from bright yellow to orange to a crimson red, it is one of natures finest displays, the deciduous trees then sleeping for the winter months. They took nutrients from the ground to assist their growth during spring and summer, and now is the time to give back to nature and this can be achieved by gathering the fallen leaves and making a leaf mulch or mould full of natural nutrients. Contribution by Oliver David Cook Lavender is without doubt one of the most popular shrubs to be found in any garden and with good reason too, providing a plethora of pleasures from the amazing aroma to the wonderful lilac flowers, particularly as they sway hither and thither in a gentle summer breeze. Planted alongside paths and walkways, as a small hedge, the perfume emitted is
therapeutic for the person, whilst at the same time attracting butterflies and bees. Planting lavender in clumps or in hedge form ensues a profusion of blossom and is more beneficial for the insects as it means they can jump from flower to flower with ease, compared to a sporadic planting plan. Towards the end of August is the favourable time to prune and harvest the flowers, the soil temperature is at its warmest and once pruned the plant will have an opportunity to grow new shoots before the approaching winter, these shoots will then spring into life the following year. Lavender angustifolia is by far the most suitable to grow here in the UK, the varieties Hidcote and Munstead being the most popular, the latter producing a slightly darker flower. Both fall into the RHS pruning group 10 classification, meaning they flower on new wood and regular pruning will prevent them from becoming too woody. The best time of day to harvest lavender for its aromatic properties is early morning, during this time the oils of the flowers are most profound. As the daytime temperature increases the fragrant oils dissipate and the flowers will then begin to open up more and this is the desired time to harvest for decorative purposes. It is important to use sharp secateurs or shears for pruning as a clean cut is essential and one must avoid from cutting too low into the wood stem section as this will prohibit any new growth which is formed on the upper section only. Aim for cutting one third of the leaf section and in doing so forming a nice evenly rounded mound for aesthetic purposes too. The cut stems and flowers can be bundled together with an elastic band or garden twine and hung for drying away from direct sunlight and in a dry sheltered location. Once the lavender has dried, approximately 3 weeks, the buds can be rubbed or shaken off and stored in a lidded jar. There are numerous applications for dried lavender with imagination being key. The reputed therapeutic benefits include induced calmness, promoting sleep and lowering the heart rate all attributing to a more relaxed state. To enhance the aromas of the house, dried lavender can be used to aid cleaning with a sprinkling of the flowers on carpet prior to vacuuming to release the fragrance. Lavender oils also have multitudinous benefits and uses and a visit to the UK’s most southerly lavender farm based here in Cornwall is highly recommended. Here a wide range of products can be purchased, providing much inspiration too. https://www.cornwall-lavender.co.uk/ Contribution by Oliver David Cook on behalf of Green Landscapes Cornwall Ltd |
